Clock + Possibility for Safe/lock

Introduction: Clock + Possibility for Safe/lock

Our project is a full functional clock. On the front there is 60 LEDs, one for every second, and on top of the clock we have placed a segment LED display that keeps track of the minutes and hours. As an extra feature we have installed a potentiometer that is connected to the LEDs and when you turn the potentiometer you control which of the 60 LEDs that is going to light. The main purpose with this extra feature was to be able to put in a secret code that would then lock up the box, like a strongbox.
